3 Claims.

The present invention relates to containers and more particularly tofolding cartons which are adapted to be readily set up to enclose andretain articles and which may be conveniently opened for withdrawal ofarticles therefrom Without destroying the effectiveness of the containeras to the remainder of the contents therewithin.

One object of the invention is to provide a carton which may be readilysealed on conventional sealing machines and thereafter opened by rippingthe side walls along a weakened line thereby to form a tray-like coverportion hinged along a line disposed intermediate the upper and loweredges of the rear wall of the carton.

Other objects of the invention are to provide a strong, sturdy andconveniently openable container in a relatively simple and economicalform. To these and other ends the invention resides in certainimprovements and 'combinations of parts, all as will be hereinafter morefully described, the novel features being pointed out in the claims atthe end of the specification.

In the drawings:

Fig. 2 is a perspective View of the carton as it appears after beingopened for the removal of the contents v Fig. y3 is a view of the cartonblank.

Fig. 4 is a perspective view of a modified form of the invention;

Fig. 5 is a view of this form of the container in a. collapsedcondition; and g Fig. 6 is a view of the blank for this form `of theinvention.

The present invention provides a convenient form cf carton which findsadvantageous use for the packaging of articles such as small packs ofcigarettes where it is desired to provide a. convenlent and attractivecontainer in which the individual packs of cigarettes or other articlesare retained in a readily accessible manner, as for example, on a shelfor table. The present carton permits a number of small packages to bereadily enclosed and retained free from dust until sold by theretailer," after 'which the carton may be readily opened in the homewhere the individual packages may be removed from time to time, asdesired. Due to the weakened. line formed intermediate the top andbottom edges of the carton, opening the carton along xsuch.-v weakenedline will form a tray-like lower 'portion and a anged cover portionarranged to freely swing on the lower wall of the lower tray portion. Inthis manner, a relatively sturdy container is formed which has agenerally smooth exterior and is thereby well adapted to receive anattractive printing design thereon simulating the ordinary small woodchests that are employed to contain small articles, such as cigarettepacks and similarly packaged. commodities.

Referring more particularly to the drawings, the carton is formed from ablank of folding bcxboard, indicated as a whole at 5. The bottom panel 6carried at its edges a front wall panel 'I, rear wall panel' and sidewall panels 9 and I0, each of which are defined from the bottom panel bythe score lines indicated.

The front, rear and side walls are secured together by attaching flaps,indicated at II, I2, I3, and [4, which, in the present instance, arelocated on the lateral edges of the respective front and rear walls 1and 8.

A top closure panel I5 is preferably provided as an extension on therear wall 8. This top is provided with a flap I6. The rear wall 8, thetop closure panel I5 and the flap I6 are defined from each other by thescore lines I'l and I8.

In order to provide forthe formation of a flanged cover upon opening.the lled carton, the front wall, the side walls and the front wallattaching flaps are provided with lines of perforations, or otherwiseweakened lines, as indicated at IB; 2D, 20; 2|, 2|; and 22, 22. When thecontainer has been set up as indicated in Fig. 1, it may be opened byrunning some instrument, such as a letter opener or thumb Inail, alongthe weakened lines until the top portion of the container has beenentirely broken loose from the lower portion, whereupon the coverthusformed, as indicated at Fig. Zmay be swung back along the hinge line 23formed by scoring the rear Wa1l8. Y

For the purpose of forming a closed joint along the lateral edges of thetop panel I5, aps 24, 24 are preferably provided on the side walls 9 andIll which flaps are secured, as by means of adhesive, to the undersideof the top panel I5. See 'particularly Fig. 2.y

The flap I6 on the front edge of the top panel I5 is preferably formedof such a, length as to extend beyond the severed portion 'Ia on thefront wall whereby the flap I6 will overlap the inner surface of thelower section `.of the front wall panel 1. The extremities of ltheexposed edge portion of the flap I6 are preferably rounded to facilitateinsertion of this flap within the lower portion of the carton. 'I'hisflap also serves to prevent undue lateral shifting movement of theflanged cover pQrtion when the cover is in closed position. v

In setting up and packing the carton, the walls 'l and` 8 are firstmoved to upright position, after which the attaching aps II, I2, I3, andI4 are folded inwardly at right angles thereto. The side walls 9 and lliare then raised to upright position and, at this time, or prior thereto,adhesive is applied so asvto cause the entire portion of the attachingiiaps to adhere to the walls 9 and I0. It

will be noted that care should be taken to cause adherence of theportions IIa and I3a with the portion 9a and, similarly, cause adherenceof the portions i2a and I4a with the portion lila, this being necessaryto properly form the flanged cover by severing walls along the weakenedlines.

The carton, as thus far set up, is now ready for the reception of itscontents. When the desired articles have been packed within the cartonthe next step is-to fold inwardly the flaps 24, 24 and to apply adhesiveon the upper surface of said flaps so that adherence will be effectedbetween them and the underside of the panel I5. Adhesive is also appliedto either the outer surface of the flap I6 or the inner surface of theportion 'la of the front wall 1 to effect adherence between this portion1a and the flap. Care is exercised not to apply any adhesive to the flapI 8 which is not overlapped by the portion 1a of the front Wall 1 asadherence between the ap I6 and the lower portion of the front wall 1would prevent ready opening of the carton.

The container, as thus formed, is illustrated at Fig. 1.

As mentioned before, the containerl is opened by breaking the front andside walls along the perforated lines, whereupon the container may beopened as indicated at Fig. 2.

In the modified form of the invention illustrated in Figs. 4, 5, and 6,the container as a whole is indicated at 25 and comprises a bottom panel25, a front wall panel 21, rear wall panel 28 and side wall panels 29and 30. vAs in the previously described form, attaching aps 3l, 32, 33,and 34 are provided on side walls 29 and 30 for the purpose of attachingthe front, rear and side walls together.

A top closure panel 35 extends from the outer edge of rear wall panel28, this flap 35 being formed with an extension flap 3B on its outeredge. Score lines 31 and 38 separate the top panel 35 from the panel 28andthe flap 36.

In order to provide for the formation of a flanged cover upon opening aiilled carton, the front wall, the side walls and the front wallattaching flaps are provided with lines of perforations or similarlyweakened lines, as indicated at 39, 39; 40, 40; 4I, 4I; and 42; 42. Whenthe container has been set up as indicated in Fig. 4,

-it may be opened by running an instrument along the weakened linesuntil the top portion of the container has been entirely broken looselfrom the lower portion of three of its sides, whereby the cover thusformed may be swung back along the hinge line 43 formed by scoring therear wall 28.

Flaps 44, 44 are provided on the side walls 29 and 30 for the purpose offorming a closed joint along the lateral edges of the top panel 35,these flaps 44, 44 being secured to the panel 35 by adhesive. See Fig.4.

" In this form of the invention, it is desirable to provide a containerwhich may be partially set .up at the carton factory and then collapsedto a fiat condition for shipment to the user. For this purpose,diagonally disposed score lines 45, 45 are impressed in the side walls29 and 30. See Fig. 6. When the flaps 3|, 32, 33, and 34 are secured tothe front and rear Walls, as shown in Fig. 5, the front and rear wallsmay bevcollapsed fiat over the bottom 2B and the central portion of theside walls will swing outwardly with the diagonal portions at the endsfolded to lie against an adjacent portion of the side walls, all asclearly shown in Fig..5. Ihe cover panel, 35, will then assume theposition shown in Fig. 5 in which it overlies the bottom 26 and frontWall 21.

The carton, upon reaching the user, may be opened up for filling, afterwhich the closure is sealed in a manner similar to that explained inconnection with the first described form of the invention.

The carton, after being lled with merchandise and sealed, as abovestated, may be opened by breaking the front and side walls away alongtheir perforated lines so that the contents will assume the appearanceshown in Fig. 4.

It is to be noted .that the diagonal score lines in the severed portionsof the side walls which are secured to the closure will becomeinoperative by reason of the fact that the ilaps 44 are adhesivelysecured to the under side of the closure panel. i

T he diagonal score lines in the lower part or tray of the container inits final form will not be operative so as to cause outward swinging ofthe side Walls so long as the tray portion of the container is lled witharticles.

From the foregoing, it is apparent that the present invention providesan economical form of carton, which, while comprising relativelyfewparts, will be effective for the purpose intended. That is, it willsatisfactorily enclose the contents packed therein until such time as itis desired to open the container, whereupon, by simply breaking thewalls along the weakened lines, a container is formed which has asturdy, flanged cover portion hinged on the lower portion or containerproper.

'While the present description sets forth a pre- -ferred embodiment ofthe invention, numerous changes may be made in the construction withoutdeparting from the spirit of the invention, and it is therefore desiredthat the present embodiment be considered in all respects asillustrative and not restrictive, reference being hadv to the appendedclaims rather than to the foregoing description to indicate the scope ofthe invention.
